A useful function in PHP parse_url_PHP tutorial

A useful function in PHP, parse_url, is particularly convenient for analysis of information capture. An example is as follows:
$url = "http://www.electrictoolbox.com/php-extract-domain- from-full-url/";
$parts = parse_url($url);
Output:
Array
(
[scheme] => http
[host] = > www.electrictoolbox.com
[path] => /php-extract-domain-from-full-url/
)

Another example:

< ?php
$url = 'http://username:password@hostname/path?arg=value#anchor';

print_r(parse_url($url));

echo parse_url($url, PHP_URL_PATH);
?>

Output:
Array
(
[scheme] => http
[host] => hostname
[user] => username
[pass] => password
[path] => /path
[query] => arg=value
[fragment] = > anchor
)
As you can see, it is easy to decompose the various parts of a URL. It is also easy to extract the specified parts, such as
echo parse_url($url, PHP_URL_PATH) ;
In the second parameter, set the following parameters:
PHP_URL_SCHEME, PHP_URL_HOST, PHP_URL_PORT, PHP_URL_USER, PHP_URL_PASS, PHP_URL_PATH, PHP_URL_QUERY or PHP_URL_FRAGMENT.
